N261 Tilburg - Waalwijk

Some new aerial photos of the N261 project. They will upgrade N261 to a four-lane, controlled-access expressway.

1. The A59-N261 interchange near Waalwijk.


2. New interchange in Waalwijk.


3. Sprang-Capelle interchange.


4. Efteling interchange.


5. Ecoduct

Feels like a lost opportunity not to have linked it with A58, making the western and northwestern quadrants of Tilburg Ring (N260) fully grade-separated as well.

Interchange Joure is the only roundabout interchange in Dutch motorway network where motorways intersects on groundlevel and it should be replaced by 2017
Some pictures:

It's probably also the only one in Europe.
One of the things I like about the Italian closed toll system is that it pushed for the creation of a contiguous network, with different motorways properly linked together. Germany, for example, has a very extensive network, but has many more gaps than Italy.

It can't be the only one in Europe, the UK, with there love of roundabouts interchanges must have some!
At the same time lots of interchanges used to be roundabouts in the Netherlands (Deil, Ouderijn to name a few), Joure is the only one that hassn't been replaced yet though!

None where both routes meet the roundabout without some sort of grade separation on at least 1 of them.

There are roundabouts at motorway-motorway junctions where the route listed first hits a roundabout, and doesn't terminate. The other motorway meets the roundabout via sliproads. Here's a list:
- M58 at the M6 (two roundabouts; effectively terminating at the eastern one, though there's the link to the A577)
- M60 junction with M62/M66 (note that this is a three level roundabout interchange and the number takes sliproads)
- M271 junction with the M27
- A627(M) junction with M62
- M4 Heathrow spur junction with M4
- M12 (NI) junction with M1 (NI) east-facing slips (technically only - functionally terminating motorway)

And where the motorway meeting the roundabout at-grade terminates (at another motorway that is grade-separated):
- M49 at M4
- M50 at M5
- M67 at M60 (roundabout not under motorway regulations)
- M69 at M1 (roundabout not under motorway regulations)
- M180 at M18
- A308(M)/A404(M) at M4
- various short spurs

The only historic example of something like Joure was the M8-M9 junction (now J1 of the M9)

A12 Ede - Arnhem

Works have started to widen the A12 motorway from Ede to the Grijsoord motorway interchange (A50). They will be cutting trees over the next few weeks. They will also survey the ground for explosives (from World War II).

The A12 will be widened from 2x2 to 2x3 lanes. Current traffic is around 85,000 vehicles per day.

I can think of several motorway junctions with roundabouts in Spain, namely the southwestern end of A-62/A-66 concurrency, A-22 eastern end at A-2, and A-68 at Z-40 (Though I don't consider A-68 a full-fledged motorway, just an expressway). But nothing like the Joure interchange roundabout.

There used to be several more of these roundabout motorway-to-motorway interchanges;

* Oudenrijn A2/A12 (rebuilt 1968)
* Ypenburg A4/A13 (rebuilt 1969, 1985, 1999)
* Hoevelaken A1/A28 (rebuilt 1971)
* Prins Clausplein A4/A12 (rebuilt 1985)
* Deil A2/A15 (rebuilt 1989)
* Heerenveen A7/A32 (rebuilt 1998)

In addition, there are several roundabout interchanges with flyovers still existing;

* Rottepolderplein A9/A200
* Leenderheide A2/A67
* Velperbroek A12/A348

There are still some other motorway-to-motorway interchanges that are partially or entirely at-grade;

* Julianaplein A7/A28 (intersection with traffic lights)
* Hooipolder A27/A59 (diamond interchange)
* Barneveld A1/A30 (parclo)

Ypenburg and Leidschendam (Pr Clausplein) were different. They were roundabouts for the A4 connections, but the A12/A13 continued underneath (grade separated).

But all those flyovers were built afterwarts. They had always been planned, but only been built after some decades. By the way, the Deil roundebout was also planned to have a flyover, but in the 80-ies it was decided to build a complete cloverleaf instead of the existing roundabout,

And still nothing planned for the A15 between Papendrecht en Grinches (with peaks over 100,000 vehicles per day, including many heavy trucks) and also still nothing planned for the A20 between Nieuwerkerk and Gouda. Two roads which are in the top-5 of the worst congested stretches in the Dutch motorway network.

Looks like they are widening the roads a lot faster for non-problematic roads all around the country (when traffic jams are the leafing indicator) and that the roads with the most problems (mostly in the Rotterdam area) are just so easily "forgotten".

What are the government workers in the The Hague thinking when they are making these plans and priorities?

I think that it is more efficient to widen 100 km of almost congested road, then to widen 10 km of fully congested road. The problem in the Rotterdam area is that there isn't much free space around the motorways, so it is very expensive to expand at all. And if a road is widened, laws require that the noise and air polution is kept under the limits, while roads who are already build can go over it. So if you want to expand the A20 and A15, you would require noise barriers and polution reduction programmes. At places in the Rotterdam Area where it is possible, it is/will be done (A4 Midden Delfland, A15 Ridderkerk-Maasvlakte, A13/A16 link).

The amount of money to solve one minute of delay per kilometer is much higher on the A15 and the A20 then it is on other roads. Because money can only be spend once, I understand the goverment's actions to widen roads elsewhere, because it will reduce the total minutes of delay per kilometer most effectively.

A27 Lek Bridge

The Lek River Bridge under construction in 1978. It is still the longest girder bridge in the Netherlands.

Remarkable, the traffic jam is usually in the other direction
